To all w from 1f/may concern Be it lrnown that I, KARL C. VoLco'r'r, acitizen of the United States, residing at Florahome, in the county ofPutnam and State of Florida, have invented certain new and usefulimprovements in Stump Pullers; and l do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

The object of this invention is to provide a novel construction of stumppuller, which will be simple in construction and thoroughly e'liicientin operation.

The invention in its preferred form is clearly shown in the accompanyingdrawings, in which:

Figure 1 is a side elevation of a stump pulling device embodying thefeatures of my invention.

Figure is a view in end elevation, partly in section, and

Figure 3 is a diagrammatic view.

Referring now in detail to the drawings:

1 designates a master wheel, provided with spokes 2 radiating from thehub 3 revolubly mounted on a shaft 41;, suitably supported in bearingsin a frame 5. Said master wheel is provided with marginal inward projecting ears G constituting bearings for the shafts 7, each shaftsupporting` lixedly joined pinions 8 and 9 of unequal pitch diameters.The pinions 8 mesh with a stationary gear 10 concentric with the hub 3and mounted thereon, and suitably secured against revoluble movement, asby means of bolts 11 passing through portions 12 of the frame 5. Thepinions 9 mesh with a gear 13 revolubly mounted on the hub 3, said gear13 being rotatable with a drum let on the shaft.

On the outside of the master wheel are gear teeth 15, in which meshes apinion 17 on a jack shaft 18, and on said jack shaft is i a pulley 19,and over this pulley passes avi belt 20, driven by a suitable source ofpower, not shown.

Secured to the drum 14, so as to be wound thereon, is a flexibleconnection 16, such as rope or chain, which may bewound around the stumpto be pulled.

In operation, it will be noted that as the master wheel 1 is driven bythe pinion 17, the pinions S travel around the stationary gear 10 andare thus rotated, said movement of rotation being iniparted to thepinions 9 meshing with the revoluble gear 13, which is` thus driven. Themovement of rotation of the gear 13 is imparted to the drum 14 whichwinds up the rope or chain thereon, thus` ra fixed gear on one side ofthe spokes and a revoluble drum on the other side of the spokes, thedrumprovided with gear teeth, planet pinions in pairs, each member of a pairintegrally joined with the other member with a reduced diameter betweenthe members of the pair, the pinions carried by the ears with the spokesextending into thc channel. made by the reduced portion, one of thepinions of cach pair coaneshing with thc fixed gear and the other of the`pinions tao-meshing vwith the teeth of the drinn.

2. .ln a stump pulling device, in combination. with a driven gear, adriver provided with spokes and carrying a planetary pinion on each sideof the spokes, the pinions integrally joined and bearing on the spokes,

a fixed gear co-meshing with one of the pinions on one side of thedriver gear, and the i driven gea-r cli-meshing with the other pinion onthe other side of the driver gear, and

ears upon the driver journalling the oversignature. j
